I've just installed CS4 update along with ACR 5.2 on my MacBook Pro,OSX 10.5.5. I am excited to get started making use of the new tools in ACR 5.2. I am fairly proficient and comfortable using CS3 and ACR 4.6.

Can anyone recommend a good tutorial or how-to book to help me get started using the new tools such as the graduated filter, adjustment brush and targeted adjustment brush?
